Less hair falling out
So far I’ve noticed I loose a lot less hair when I shower or brush my hair. The only downside is that I go through it very fast

The Kerastase Serum Fortifiant Hair Serum has been a game-changer for my hair care. It feels lightweight yet powerful, providing noticeable strength and shine to my hair after just a few uses. I love how it reduces breakage and leaves my hair feeling silky and manageable without any greasy residue!!

I love everything about it!
[This review was collected as part of a promotion.] I have a very sensitive scalp and have struggled with a severe hair loss this fall, so I was hesitant to try new products. However, the Kérastase Serum Fortifiant has been a game-changer. It’s incredibly gentle on my scalp—no irritation or discomfort at all—and I’ve noticed a significant improvement in my hair’s strength and growth. It’s lightweight, easy to apply, and truly delivers results. I myst mention that first I used the ampoules against hair loss also from Kerastase. I feel like those helped to stop my severe shedding and then I’ve continuously been using this serum to keep up with the results and increase new hair growth. Highly recommend for anyone dealing with scalp sensitivity and hair loss!

Heavy alcohol smell
The first 2 ingredients are water and alcohol. Its drying out my hair and the smell lingers long. I couldn't continue after 3 uses. Its been raved by influencers and I just trusted without doing my research.

Miracle worker!!
I’m on my second bottle and i have SO much new growth. One bottle lasted me a little less than a month and I even use a little less than it says to. With the price I am sad how quick it goes and wish there was a bigger size. Even my hairdresser was insanely impressed! I use this with the night serum and I’ve had 3-4” of all new growth come in! This is a must have and staple! I was losing hair like crazy on my weight loss journey and this saved the day!! I also LOVE this doesn’t make your hair greasy AT ALL! You can use it day or night.

I have actually been using it for 3 months now and I wanted to wait before writing a review to make sure it wasn’t short results. My hair feels amazing with this product and several other products I have tried dried my hair out so I 100% recommend this to anyone with hair fall out.

Amazing
Kérastase’s hair serum is a game-changer for anyone looking to transform their hair care routine. Infused with advanced nourishing ingredients, it deeply hydrates and strengthens hair, leaving it incredibly soft, smooth, and shiny without feeling greasy. The lightweight formula absorbs quickly, making it perfect for all hair types, from fine to thick, and it helps control frizz while enhancing natural texture.

Amazing Product
I use this 2-3 times a week. It smells amazing and I ALWAYS get comments like, “your hair smells so good!” every time I apply it. Keeps my scalp healthy and hair growing strong.

I did see a improvements
I liked the serum, I can't say that the problem with hair loss has been solved, but there is an improvement. For best results, the serum should be used once every three days or more often.

Fabulous smells
In addition to helping me restore the health of my hair, it also leaves a wonderful scent on my hair.

I PAID FULL PRICE! What MAGICAL SERUM is this?!!
This is a REAL RARE REVIEW*** Fantastic! I’d read review after review of this, then it kept coming up in my social media feeds. Untrusting me wondered if I was just a victim of sponsered paid influencers and algorithms but I decided to give it a go to see// IT WORKS!! Incredible stuff. My hair fall is hardly any at all anymore after using this daily for 2 weeks. It’s very light, I use it everyday (massage into your scalp with freshly washed hands and fingers;) them prepare for the magic to happen. I’m hooked!

It’s an OK scalp serum
[This review was collected as part of a promotion.] I like that this serum doesn’t leave my hair greasy like the OUAI scalp serum or other serums, but I don’t love the fact that the scent is super strong. It smells good, but it’s too much sometimes and it makes me nauseous. It’s also pretty expensive. I don’t notice hair growth with this like I do with the ouai serum. So I feel like it’s okay. It doesn’t do anything positive, but nothing negative.

So happy I purchased!!
[This review was collected as part of a promotion.] My hair was falling more than usual, so I decided to give this a try & I am so happy I did! The hair falling has definitely reduced and I have noticed my hair feeling thicker and healthier. I will be repurchasing & keeping part of my nightly hair routine!!

Smells great
A little tricky to use as it’s super liquidy and I couldn’t keep it in my palms to transfer onto my ends. Does smell great tho

Exceeded my expectations
[This review was collected as part of a promotion.] If you have dry, frizzy hair that falls out a lot, I recommend that you buy this serum, my hair looks shinier, the frizz has diminished and less hair falls out. I am very happy with my purchase

Serum
I just received it and try on the serum, the smells is fantastic. It makes my scalp has a clean feelings and even ready to go out without any perfume on. I will need to use it for a period of time to see if it helps, I sure will come back and write another review

I think it’s working
Been using this alongside the genesis mask. I think this has been helping my hair as I’ve noticed less breakage but will probably take some time.

Best hair serum I ever had
[This review was collected as part of a promotion.] After using it for 6 months, most of my friends said my hair grows more. I can also feel that this product does not contain harmful chemicals. It won’t irritate my head like other brands. I will keep using it consistently

Very watery
This is too liquid for my taste. Also left my hair feeling dry.
